Some mailing list software has the so-called VERP capability, in which "From: " headers contain the recipient address, encoded thus: From: List Name <[EMAIL PROTECTED] or some such. The MTA at listhost has to be set up to deliver anything with a "+" delimiter in the local-part to the local address preceding the "+". This sort of delivery arrangement is quite common, possibly a majority of MTA software accomodates such. The list server can then decode who the mail was sent to, except in the most pathological of multi-gatewayed goshawful bounces. The load on the list server is higher, as each message must be originated and delivered individually, rather than as batches with multiple envelope-recipient on a single piece of mail, and that in itself may forbid using such an arrangement on the heavily loaded SF mailing list servers. However given suitable choice of list server and MTA, no scripting is required, merely turning on some configuration settings, and such bouncing members are generally removed with no intervention on the part of the list maintainers required. I don't know whether this is possible at SourceForge, but if it is, it might make sense to turn on these settings once in a while. -- ----------------------------------------------------------------- Dan Wilder <[EMAIL PROTECTED]> Technical Manager SSC, Inc.
